While none is yet a drop-in replacement, a PC World article looks at ways that some administrators can get a cost advantage by switching.

"So am I to understand that less-than-clear MS page that the Exchange CAL's are valid forever and you only pay for them once?"

The page is quite clear actually, with price lists and everything.

Yes, you only pay for CAL's for a version one time. For example, if you have 50 users, we will keep it small, and are using Exchange 2007, once you buy those CAL's they are good until you upgrade your Exchange, which is normally about every 5 years or so.

With Zimbra, you pay that price per user every year, so over 5 years, it is more expensive than Exchange in per user costs.
